I'm asking this now because I'm heading to the Florida Keys for a dive vacation in May and will not be able to afford both a strobe and lenses before that, but will be able to afford one or the other.
Cheers,

Your underwater photography will improve about 1,000% with a strobe. The colors will really start to "pop" in your photos like you've never seen.
Learning to use a strobe does take some work and practice, but those lenses won't do you much good without some light.
My opinion.

Strobe. Not much point to a wide angle lens without it.
Definitely strobe - it's the difference between good photos and great photos.
